Case reportParatesticular leiomyosarcoma in an elderly man
Section snippets
Case report
The patient was a 71-year-old African-American man who presented with an oval, nontender mass clinically confined to the left epididymis. His past history was significant for left epididymitis and urethral stricture treated by surgery. He denied any history of testicular trauma. The digital rectal examination revealed a benign enlarged prostate. Approximately 10 months later, scrotal sonography showed a 3 to 4-cm mass with increased echogenicity arising from the epididymis of the left testis.
Comment
We reviewed the published studies for reported cases of paratesticular leiomyosarcoma (Table I). Among the paratesticular sarcomas, leiomyosarcoma is the second most common sarcoma in frequency, preceded by liposarcoma; however, it is the most commonly reported histologic type followed by liposarcoma and rhabdomyosarcoma.1 Few cases of paratesticular leiomyosarcoma have been reported.2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 Leiomyosarcoma is a soft-tissue tumor arising from smooth muscle cells
